Redneck Travel Company

 Where will you take a vacation? Rio? No problemo, log onto the io exchange and shad off a chunk of short chain Btc,  locked for two weeks.  Exchange change it back to the Rio exchange after two weeks.

All the tourist vendors take it, they don't care much about Btc volatility over two weeks. The Rio exchange will aggregate on the short chain and the vendor trades for local tax currency. I think we can do this stuff with the new block chain protocol, public chain Spectre proofing. They have some neat share signature contracts, time locks and counts.  These folks are just absolutely aiming at the international travel market, and the appeal of a local exchange for higher speed one step money exchange is great, beats MasterCharge.

I see some blow out stuff here, especially with the market niche Btc has, FX exchange. The new Taproot block chain algorithm has just enough, no more.  This is a bit of a shaking in the industry.

Expand the concept for general trade. Two international parties can make contracts conditional on neutral Btc, so Btc becomes a useful hedging tool for currency risk.

The new code has an interesting feature. The contracts have signature requirements, agreements confirmed. They are multi sig enctypted and one party that meets a condition can decode its part with verification, without revealing the other conditions in the contract.

So, there is a compilation trick, for a bare bones provable contract, all parties must supply signatures, and the contract rolled up with signed parties, not necessarily all equally conditional at all sable points. Thus, the decoding is meeting conditions and executing an exit, but in the ready form, only you needed to decode the critical section.

This is going beyond standard simple ledger, like I say, well done, it exactly meets the skeleton of public ledger contracting. And it is not getting in the way when not used, it is not overly expressive. It solves the great bulk of one two two and three step commercial protocols. Treating the contract language like a culminating network protocol, tht is their secret.

Spawning the third party industry.

Contract pros, combination trader, lawyer, logician.  The range of tools that we can use, designing contracts over this Btc Taproot will be very interesting, where accountants want this for their clients. From stock options to candy purchases to real estate.  Btc makes the byte code interpreter, the function is the network protocol over ledger nodes. Pure, unadulterated sandbox, public Spectre proofed..
